Plans to try and stop migrants from crossing the Channel went awry, with the French digging their toes in over UK plans to turn back some boats. The government wants the Border Force to turn away boats - but only in limited circumstances under a pre-authorised policy, signed off by Home Secretary Priti Patel. France said this would break international maritime law, and also accused the UK of financial blackmail. Boris Johnson's spokesman said that any new plans would be safe and legal. Today, we remained on a three-line whip, with Government business still to be voted on. I dropped into the Chamber just after midday to hear a Statement on the new, light tank AJAX. As a member of the Defence Committee, we'd already heard from Minister Jeremy Quin that the programme was in trouble. We'd been told that noise and vibration was actually injuring crews with hearing loss and back pain. Mr Quin made no secret of the issues was very upfront during this comments. While he could not promise that the £3.5 billion programme would not be axed, he did say that manufacturer General Dynamics would do all it could to rectify the faults. I was called to ask a question and that is on my website. My concern is for the poor taxpayer. The minister was unable to reassure me as the contract is understandable sensitive. My colleague Mark Francois, himself a former defence minister, was less obliging, castigating the failure of this programme and others. To date, only 26 of the 589 tanks have been delivered. The history of MOD contracts is littered with expensive failures and I sincerely hope this is not another! We dropped to one-line in the afternoon, when I hopped on to my motorcycle and headed home. In Scotland, we heard that people there would need proof they have been fully vaccinated before they could enter nightclubs and many large events from 1 October. The vaccine passport plan was formally approved by Holyrood after the SNP and Greens voted in favour. Some businesses complained of a lack of detail about how the scheme would work in practice, and I am not surprised. I oppose vaccine passports, so too were the Conservatives, Labour and Liberal Democrats in Scotland. In Afghanistan, dozens of international passengers - including UK citizens - flew out of Kabul in the first such flight since US forces left the country. The Qatar Airways charter flight landed in the Qatari capital Doha today, with a second flight due tomorrow. Reuters news agency reported that 113 people were on board the plane.
